Title: Improvements in or relating to the distillation and carbonization of mixtures of oil with coal or similar carbonaceous material
IPC: C10B55/02
Filed: 1934-08-29
Abstract: Halogenated hydrocarbons are obtained by passing the gases containing unsaturated hydrocarbons, obtained in the destructive distillation of coal-oil mixtures, through scrubbing towers in counter-current to a stream of bromine or chlorine water or brominated or chlorinated sea water or brine.ALSO:Coke, hydrocarbons, and halogenated hydrocarbons are obtained by mixing coal and oil, stirring the mixture while preheating to 100--325 DEG  C., coking the mixture in a stationary retort at temperatures between 450 and 650 DEG  C., condensing the components of the distillate liquefiable at ordinary temperatures, and recovering the unsaturated compounds in the residual gases and vapours by passing these through reaction vessels while being treated with halogens or sulphuric acid, an atmospheric or negative pressure being maintained.  Coal <PICT:0448029/III/1> fed from a hopper 2 is mixed with oil, preheated in a vessel 7, in a mixing vessel 5 and the mixture is preheated in a vessel 14 provided with a stirrer 15 and heated to 325 DEG  C.  Vapours pass off through a reflux condenser 16 maintained at a temperature which refluxes products boiling above 200 DEG  C., to the vessel 14, and a pipe 17 to a fractionating tower 18 having upper and lower packed sections 25, 26.  The preheated mixture passes into a coking chamber 21, which may be provided with a removable steel tray, where it is heated to 600 DEG  C., and reduced to coke.  The vapours and gases produced pass through a line 22 to the column 18 from which condensate is recycled through a cooler 28 to the vessel 7. Vapours pass through a cooler 32 and the condensate is collected in receivers 34 from which the gases pass upwardly through a packed tower 49 down which a stream of chlorine, bromine, or sulphuric acid is passed in countercurrent.  The gases pass finally through a refrigerator 50 maintained at about -40 DEG  C. and condensate is collected in a receiver 51.  Brominated sea water or brine may be used in the towers which are preferably cooled.  The yield of the product may be modified by the addition of catalysts, e.g. zinc dust, ferric oxide, to the coal-oil mixture or the vapours may be passed through a heated catalyst tube 56.  The gases and vapours may be passed through a byepass 54 direct to the tower 49. Specification 448,028 is referred to.

Abstract: 299,964. Bowden Wire, Ltd., and Nisbet, A. H. Sept. 23, 1927. Cone and disc. - A steering-damper, shockabsorber, vibration-damper, or brake for vehicles, machinery, shafting, &c., comprises conical friction surfaces adapted to be brought into engagement by means of a cam and Bowden or like transmission mechanism, the parts being constructed and arranged in the following manner. The application to a steering-damper for motorcycles &c. is shownr in sectional elevation in Fig. 1 and underside plan view in Fig. 2. A slotted sleeve 10 is mounted on the steering-column 11, and is provided with a truncated conical portion 13, on which is mounted a similarly-shaped ring or,clamp 15, the outside of which is of double conical shape, and co-operates with the inner surfaces of two half-ring like members 19, 20 pivoted together at one end on a stud 23, the other ends 24, 25 being movable relatively to one another to grip around the member 15. For this purpose a cam 27 is disposed in a hole 26 in the end of the member 20, and is actuated by an arm 28 pivoted on a stud 29 on the member 19. the free end of the arm 28 being connected at 33 to one member, such as the inner cable 35, of a Bowden transmission, the outer member of which is secured to an adaptor 31 adjustably screwed into a block 32 adapted to swivel on the stud 23, a spring 37 being incorporated. The member 19 is anchored by a bar 40 and a clip 43 to the top tube 42 of the cycle frame. The cam 27 rocks the member 20, and the members 19, 20 are thus closed upon the member 15, the parts being so constructed and spaced that the member 15 is forced downwards to grip the conical part 13 of the sleeve 10. The joints are enclosed by means of a washer 38 and a nut 39. A screw 46, adapted to engage a face 47 of the member 20, is adjusted to regulate the travel of the member 20, the return of which is assisted by a spring 48. In a modification, the cam 27 acts on the member 20 through a spring-pressed plunger.

Filed: 1964-06-22
Abstract: 1,008,617. Rotary filter. I. WALLQUIST. June 22, 1964, No. 25687/64. Heading B1D. The cylindrical surface of a drum 3 comprises coarse filter cloth and the drum rotates in a basin 1, filtration of liquid delivered to inside the drum being effected by solids carried in the liquid and forming a layer on the cloth. The solids may be those contained in the turbid liquid or cellulose fibres added thereto. Liquid enters drum 3 down shaft 4, on which drum 3 rotates, and through openings 7. Liquid which has passed through drum portion x, where the solid layer is thin and filtration poor, is diverted by partition 26 into space 15, from which it is pumped back to the drum inlet, Fig. 4 (not shown). Liquid passed through region y, where the solid layer is thick and filtration good, is similarly diverted to space 19 and is then used by sprays 21, 22 to backwash the drum, most of the solid entering funnel 8 but some (spray 22) re-entering the liquid in the drum, where it is needed to quickly build up a layer at portion x. The bulk of filtered liquid leaves basin 1 by valve 11, which is controlled by a float 12 in the drum to maintain a constant level. Partitions 26, 27 are suspended from floats 30, 31. In Fig. 1, not shown, the partitions are replaced by shields extending to the drum surface. The drum may be backwashed using air, and the best filtered liquid, from space 19, used for other purposes.

Filed: 1971-04-19
Abstract: 1340138 Disposable diaper PROCTER & GAMBLE CO 19 April 1971 [1 April 1970] 25758/71 Heading A5R [Also in Divisions A3 B1 and G1] A disposable article comprises a translucent backing sheet 2 of water-impervious material, an absorbent pad 3 and a small amount of moisture-actuated indicating agent 1 distributed over some or all of the area of the article and positioned between the backing sheet and the pad. The absorbent pad 3, which comprises plies of wadding prepared from wood pulp fibres is enveloped on its moisture-receiving surface by an inner sheet 4 which consists of a porous, non-woven fabric. An adhesive edge fastening (5) serves to attach absorbent pad 3 to inner sheet 4 and also to backing sheet 2. The dye particles 6 of the indicating agent and, if present, the diluent masking agent particles 7 used to mask the colour of the dry indicating agent until wetted are situated and mechanically and electrostatically retained between the surfaces of the absorbent pad and backing sheet. The indicating agent, which may consist of certain vegetable and food dyes, may be extended over the entire outer surface of the absorbent pad, or preferably, in order to reduce the amount of indicating agent used and to eliminate the possibility of skin contact and staining, can be placed in smaller indicating areas (8). When the indicating agent is exposed to liquids penetrating the absorbent pad, the dye, or the dye and the diluent masking agent, is dispersed and the colour of the resulting dye solution seen through the backing sheet thus indicating soiling by wetness. The dye in the moisture-actuated indicating agent can be, e.g. intro, monoazo, diazo, phthalocyanine, quino -line, xanthene, triaryl methane, indigoid and vegetable dyes such as carotene, chlorophyll, tea and coffee. Suitable diluent masking agents can be talcum, whiting, silica, sugar, salt and starch.
